I believe in God - who reveals himself in the orderly harmony of the Universe. I believe that intelligence is manifested throughout all nature. The basics of scientific work is the conviction that the world is an ordered and comprehensible entity and not a thing of chance.

I am going to give you some tips on how to be confident on working at different sites which are away from your hometown.

Suppose you are posted on a site in a location where you are not familiar with the local language ,

How to work at such a site ?

Will there be communication problems ?

This video shall teach you how to survive and work efficiently there.

There are five tips given in this video by which you can work effectively there.

Read this ” Main language at the site is of course English because the all the drawings are in English so some words are from English at every site for example : the work site , construction ,building ,cement Steel , rebars , reinforcement, concrete , RCC ,PCC, excavation wooden, ceiling , compact , compaction , rings , bar bending schedule , drawing, architect , consultant , contractor , fitter carpenter, shuttering , centring, plates , oil these are very common words and their where ever you go these words are required”

Thank you for giving a great response to this series on unemployed civil engineers.

This is the 4th session and today we shall be talking about concrete.

Concrete can be planned either as a Design mix or a Nominal mix.

Design mix is more accurate since each of the constituents has been properly tested in the laboratory.

the Nominal mix is basically an imperial method of design. It assumes that the cement is of Grade 33 whereas now a days , this grade is not manufactured.

What we see at site is either Grade 43 or Grade 53 OPC .

Concrete and water is yet another topic where we need to focus.

Remember one thing : Strength of concrete and water added in the concrete are inversely proportional to each other.

Workability is one word which needs clarity.

It is the ease with which you can place or finish the concrete.

Workability means the flow of concrete.

The flow of concrete can be measured by the slump value.

Concrete can be manufactured at the site or it can ordered directly from a batching plant which is also known as a ready mix concrete plant or RMC plant.

First video is about the transit mixer .

The transit mixer is a truck which is mounted with a drum and through this TM , the concrete is transported or supplied to your site.

Another video shall show you how the casting is done in Hammered piles on the banks of the River Godavari. You can first see the concrete being shifted by trolleys to the Piles and then lowered down with the help of tremie pipes.

Both the videos have proper captions so that each frame and object is understood to the viewer.

Please remember to read the description below this video. you shall find plenty of links to the relvant material on concrete.
